CHARLES KELLIHER Patented Dec. 25, 1951 UNITED STATES OFFICE 4 Claims.

In addition, this type of sash, when open to admit air is completely removed from the closed position to afford no protection against rain and the like. Accordingly, it is an object of this invention to provide a window assembly which is swingably mounted to permit a sash to be opened across substantially the entire window area.

It is a further object of the invention to provide a window sash which is adapted to be swingably opened in either direction.

It is another object of the invention to provide a window sash which is adapted, to be opened across substantially the entire window area and simultaneously to protect the window area from ram.

An additional object of the invention is to provide a window sash which is adapted to admit and direct a draft of air in a predetermined direction.

Further objects of the invention as well as the construction, use, and operation thereof will in part be obvious and will in part become apparent.

from the following disclosure.

For'further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a perspective view, showing a window assembly according to the invention.

Fig. 2 is a horizontal section, taken on the line 22 of Fig. 1.

Fig. 3 is a fragmentary perspective view of a portion of a side member of the sash, equipped with an attachment pursuant to the invention.

Fig. 4 is a vertical section, taken on the line 4- of Fig. 3.

Fig. 5 is a fragmentary perspective view of the sash side member of Fig. 3, but with said attachment removed.

Fig. 6 is a fragmentary perspective view of a vertically slidable window frame member for pivotal connection to a side of the sash.

Fig. 'I is a fragmentary elevational view, partially broken away and partially in section, showing the side of said window frame member remote from the observer in Fig. 6.

Fig. 8 shows the attachment mentioned above in briefly describing Fig. 3, looking toward the inner side thereof, that is, looking toward the left in Fig. 4.

Fig. 9 is a horizontal section, taken on the line 9-9 of Fi 8.

Fig. 10 shows the sash side member of Fig. 3 and the window frame member of Fig. 6, coupled; this view being a horizontal section taken on the line llllll of Fig. 3 and as though on the line Hl|0 of Fig. 6.

Referring to the drawing more in detail, the window assembly as a, whole is designated 20, the same comprising a window glass 2| or the like mounted in a frame or sash22, which in turn is swingably mounted in an outer wall frame 23 as will hereinafter be described. Also mounted in the outer frame 23 is another window member 24, for example, an upper member positioned over the swingable window 2t. This second 1 window may optionally be a fixed window or a swingable window such as the window 2|, and it is understood that the features described hereinafter for the first window member may likewise be included in the other window member. Similarly it is understood that this second window member 24 may be omitted, in which case the window frame 22 may be mounted in an outer frame 23 on all sides thereof.

Considering that side of the sash 22 which, marked 22', is at the right in Fig. 1, the same is connected, in a manner later to be described, to a window frame member 2t guided for up and down sliding in the window frame 23 as by way of fixed stops (not shown) in the window frame such as employed in the ordinary window frame for the ordinary sliding sash. Said window frame member 23 will below be called the runner member.

The runner member 23 is shown as hollow and formed say of sheet metal, to have the cross section illustrated in Figs. 6 and 10.

Extending longitudinally of the runner member 23 is a shallow groove 25, and extending longitudinally of the side sash member 22' is a deeper groove 26 which aligns with the groove 25 when the sash 22 is arranged as shown in full lines in Fig. 1.

A combined weather-strip member and locking means is normally positioned in both the grooves 25 and 26 with the sash arranged as last mentioned, whereby rotation of the sash is prevented and at the same time the window assembly is made substantially weather proof.

Said weather strip member comprises, a long flat metal strip 21, below called the locking strip, having a projection or car 28 (Fig. 6) apertured at 29. Said ear is always in a cavity 38 (Figs. 4 and 5) in the sash member 22'; the cavity as near its top terminating in a shoulder 3i and thereabcve being somewhat enlarged.

Entered into the aperture 23 is the offset end 32' of an arm 32 swingable in a plane parallel with the bottom of the cavity 30. Said arm, which may be a bent length of a still metal wire, is secured to a post 33 rotatably carried by a face plate 34 seated on the shoulder SI of the cavity 30 by screws 35.

On the post 33 is a coil spring 35, having one end hooked to the arm 32 and its other end hooked to a stud 37; said spring being so coiled and connected that the post 33 is normally urged toward rotation in the direction of the arrows 35 of Figs. 3 and '8, thereby to cause the efiset end 32' of the arm 32 normally to disposethe locking strip 2? partially projected from the groove 26 as shown in Fig. 3 so to hold said strip also entered into the groove 25 as indicated Fig.6.

Thus, normally, the '22 may not be rotated relative to the runner member Suitably fixed to the plate 3% and projected from the underside thereof (as are the post anclth'e stud 37), is 'a sleeve 3%, endwisely movable within which is a cylindrical plunger ie carrying an enlarged head 3 beyond the outer "side "of the plate 3 5, such head for use as a pushbutton. Normally, the parts are arranged as 'shown'in Figs. 4, 8 and 9, and with the spring urged swing of the arm 32 in the direction of the arrow 38 of Fig. 8 limited'by the engagement illustrated between the "arm 32 and a slot ll extending transverselyof the inner end portion of the plunger 51).

Said slot in cross section is substantially shaped, one leg 4! a of which V, that nearer the inner end of the plunger 66, is at a relatively small angle to a plane perpendicular to the axis of the plunger, to hold the arm 32 againstloss from the slot. The-other leg M of such V is at a relatively small angle to said axis, to constitute a cam means relative to the arm '32 when the button. 49' is pressed to project the plunger deeper than normal-into thecavity 3B. Said cam means then acts to swing the arm 32 in a direotion opposite to that of the arrow -38 of Fig. 8, thereby to retract the locking strip 2'! wholly into the groove 25 and so to disengage said strip completely from the groove 25.

It makes no difference which end of'the strip 27 is first retracted fully into the groove'ZE, inasmuch as said groove fits reasonably close behind the strip, so that neither end of the strip may be retracted much in excess of the other end thereof. For example, if the upper end of the strip is first retracted fully into the groove 25', this upper end bears against the rear wall of the groove and acts as a fulcrum of rotation to swing the remainder of "the strip runy within said groove.

When the sash 22 is thus-unlocked from the ru'nner member 23 such unlocking maintained while the button '30 is held manually depressed,

said sash may be rotated for opening the window as desire'cLas forinstance shown in dot and dash li'nes i'n Fig. 1.

The pivotalmount'fo'r permitting this, at the 4 right hand side of the window in Fig. 1, comprises apivot member 44 (Figs. 3, 5, 6 and 10) in the form of a headed bolt 4 riveted over at M (Fig. 10) behind a plate 55 attached as at 46 in a recess 41 (Fig. 5) in the sash side member 22; said recess leading to a cavity 48 for accommodating the headed overend M of the bolt. Said bolt, after passing through the plate 45, traverses an aperture 49 (Fig. 6) through the runner member 23 and then traverses apertures through a saddle plate 56 and a strap member 5| (Figs. 7 and 10) both inside the hollow interior of the runner member 23 As shown in Fig. 7, a twisted-8 hook 52 is at tached to the upper end of the strap member 5|, and also to a suitable flexible element, as a chain 53, leading to a sash weight (not shown) or the like.

Precisely similar attachments to those above described as applied to the side of the sash 22 at the right in Fig. 1, that is, the attachment of Fig. i and the attachment of Fig. 10, are applied to the other side of the sash, as indicated in Fig. 1 in the case of the attachment of Fig. 3. As will be understood, the bolt id and the corresponding bolt at the side of the sash. 22 at the left in Fig. 1 will be in line with each other, so that together they will provide a single horizontal axis of swing for said sash.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
